Structure and Properties of Thin Films Consisting of Single Crystalline BaTiO3 Nanocubes
Abstract:
Single crystalline BaTiO3 nanocubes, which were synthesized by hydrothermal reaction with organic surfactants and additives, were assembled in order and directly on the substrates by dip-coating method using the dispersed solution. After evaporation of solvent, the orderly assembly of the nanocubes was developed over the large region in about several tens of micrometers square. It can cover whole surface of the substrate. The microstructures of the nanocube assemblies were evaluated by scanning electron microscopy (SEM) and atomic force microscopy (AFM). Electrical property of the nanocube-assembled film was characterized by piezoresponse force microscopy (PFM). The d33-V curve showed ferroelectric hysteresis and saturation behaviors under high applied voltage.
